Besides the second law's issue with SR, are Newton's 3 laws still considered to be true FUNDAMENTAL laws of motion? If not, why?
Isaac Newton is known for his three laws of motion, which describe the fundamental principles of how objects move in the physical world. He also developed the theory of gravitation, explaining the force that governs the motion of planets and other celestial bodies.
Newton's laws of motion and theory of gravitation laid the foundation for classical mechanics, which is still used to understand the motion of objects on Earth. His work also influenced other branches of physics, such as optics and thermodynamics.
Newton's laws of motion are still considered valid and are used in many practical applications, such as engineering and space exploration. However, they have been refined and expanded upon by later scientists, such as Albert Einstein's theory of relativity.
Newton's theory of gravitation was based on the concept of a force acting between two objects. However, Einstein's theory of general relativity introduced the idea that gravity is not a force, but rather a curvature of space and time caused by massive objects. This has greatly expanded our understanding of gravity and its effects on the universe.
There are ongoing debates about the role of Newton's laws of motion in understanding the motion of subatomic particles and objects moving at very high speeds. Some scientists also question the validity of his theory of gravitation in extreme situations, such as near black holes. However, Newton's contributions to science are still widely recognized and celebrated.
